I have a 1979 W116 300SD, chassis has 334k miles and rebuilt engine around 100k. When I purchased the car, the vac switch that attaches to the firewall that helps control the ALDA valve is missing. I have read various articles describing the pro and cons. I am afraid to 'step' on it in fear of what may happen. Should I replace the switch? Or what would you do?
